Fundamental Study on Arsenic(III) Halides (AsX3; X = Br, I) toward the Construction of C3-Symmetrical Monodentate Arsenic Ligands

Arsenic ligands have attracted considerable attention in coordination chemistry. Arsenic(III) halides are the most important starting materials in the preparation of monodentate arsenic ligands. In this work, we optimized the synthetic methodologies of arsenic(III) halides (AsX3; X = Br, I) and examined the difference of their physical properties such as solubility to organic solvent and reactivity to nucleophiles. In addition, a wide variety of monodentate arsenic ligands were prepared with the obtained AsX3. Finally, the obtained monodentate arsenic ligands were utilized for copper-free Sonogashira cross-coupling reaction in the reaction system with porphyrin. The results showed that monodentate arsenic ligands have higher catalytic activity compared with triphenylphosphine because of the difference of the electronic features of lone pairs between arsenic and phosphorus atoms.

Synthesis, properties and application of electronically-tuned tetraarylarsonium salts as phase transfer catalysts (PTC) for the synthesis of gem-difluorocyclopropanes

Preparation of gem-difluorocyclopropane from α-methylstyrene and chlorodifluoromethane was investigated under basic two-phase conditions. Although simple tetraalkylammonium salts appeared uneffective as phase-transfer catalysts (PTC) for this purpose, tetraphenylarsonium chloride displayed moderate activity, and inspired studies of the phenomena. To improve its efficiency we synthesized set of electronically-tuned tetraarylarsonium analogues. Their preparation revealed interesting exchange process of aryl substituents on the arsonium center, whereas activity studies demonstrated a correlation of catalytic efficiency with electronic effects of the substituents. Two of the tetraarylarsonium catalysts were characterized by X-ray studies.

Formation and Reactions of Diorganophosphinite Ions in Liquid Ammonia. Synthesis of Triorganophosphine Oxides by the SRN1 Mechanism

The reaction of triphenyl- and tribenzylphosphine oxides with alkali metals in liquid ammonia gave diphenyl- and dibenzylphosphinite ions, respectively, in high yields and a small amount of deoxygenated products.These ions reacted under photostimulation with aryl halides by the SRN1 mechanism to give aryldiphenyl- and aryldibenzylphosphine oxides in good yields.With tribenzylphosphine oxide, by consecutive debenzylation with alkali metals followed by photostimulated reaction with aryl halides, all the benzylic moieties could be replaced by aromatic moieties to finally obtain unsymmetrical triarylphosphine oxides.
